    BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

    Background: The aim of the study was to analyze the expression of nuclear receptor interacting protein 1 (NRIP1) and its partner ligand-dependent nuclear receptor co-repressor (LCOR) in endometrioid endometrial cancer and to investigate their association with estrogen receptor (ER), progesterone receptor (PR), Ki-67, clinicopathological parameters and patient survival. Materials and Methods: Immunohistochemical evaluation was carried out to investigate the subcellular expression of NRIP1 and LCOR in endometrioid endometrial cancer samples. Statistical analysis was used to identify the correlations of NRIP1 and LCOR expression with clinicopathological variables and to estimate the survival rates. Results: Endometrial cancer tissues exhibited higher expression of NRIP1 and LCOR in comparison with the normal tissues. Cytoplasmic LCOR expression was positively associated with ER and PR expression, while cytoplasmic NRIP1 expression was positively associated with ER expression. Moreover, cytoplasmic expression of NRIP1 was positively associated with Ki-67. Conclusion: Our study demonstrated that high cytoplasmic expression of LCOR may predict a longer overall survival of patients with endometrioid endometrial cancer. Patients with tumors expressing low levels of LCOR showed a worse survival compared to those expressing high levels. © 2021 International Institute of Anticancer Research. All rights reserved

    Changing the way we train surgeons in the 21th century: A narrative comparative review focused on box trainers and virtual reality simulators

    The traditional method of acquiring surgical skills by observing and assisting in surgical procedures involving human beings has been challenged during the past several years. Lessons obtained from aviation suggested that the use of simulators is related to reduced costs, increased efficiency in performing certain tasks and above all safety. A shift in paradigm is also required in modern surgical training. The development of endoscopic surgery allowed for the incorporation of medical simulators into training programmes. A review of the literature was conducted using specific inclusion and exclusion criteria, for articles published up to July 31th, 2018. Relevant studies were identified using computerized bibliographic searches of MEDLINE database. The keywords that were used in various combinations were: “Medical Simulators”, “Surgical Training”, “Laparoscopy”, “Surgical Skills”, “Box trainers”, “Virtual reality simulators”, “Surgical Education”. Surgical training with box trainers and/or virtual reality simulators confers a significant benefit in terms of surgical skills development, increases patient safety and reduces costs. Nevertheless, the use of virtual reality simulators was significantly more expensive. Simulation training allows trainees to learn from their mistakes, to repeat surgical tasks multiple times so as to establish muscle memory, and enhance skill competency with the aid of informative feedback. Simulators are necessary for the development of the skills required to meet the specific needs of endoscopic surgery in the 21st century. Teaching hospitals should introduce simulation training programmes in order to increase efficiency, reduce costs and improve patient safety. As medical advancements continue to transform the way we perform surgery day by day, simulation training will play a pivotal role in every surgical specialty. © 201

    DWBA ANALYSIS FOR SINGLE-PARTICLE TRANSFERS INDUCED BY B-11 ON MG-26 AT 114 MEV

    Detailed angular distributions using a position sensitive counter telescope were measured for all four possible single-nucleon transfer reactions induced by a 114 MeV 11B beam on 26Mg. Dififractive oscillations observed in the transfer data are reproduced by the distorted-wave Born-approximation analysis. A well determined class of optical potentials, which are strongly absorbing in the nuclear interior but nearly transparent at the surface were obtained by fitting the entrance channel elastic scattering data. Spectroscopic factors for final target states were deduced, in good agreement with those obtained from light ion experiments. © 1975

    Management of locally advanced breast cancer of the inferior quadrants after neoadjuvant chemotherapy with "B.E.B.A. omelette" Zervoudis oncoplastic technique

    <p><i>We present<strong> </strong>a new technique of oncoplastic surgery for very large tumors of the inferior quadrants of the breast that, after neoadjuvant chemotherapy, allows a good cosmetic result with oncologic safety. This "B.E.B.A. omelette" Zervoudis  technique is a mixture of oncoplastic surgery techniques resulting in large excision of breast tissue with a relatively small scar and no complications. More cases could confirm its value in the palette of the oncoplastic methods for large tumors of the inferior quadrants of the breast.</i></p&gt

    Cervical pathology following HPV vaccination in Greece: A 10-year HeCPA observational cohort study

    No full text
    Background: In Greece the population-level impact of HPV vaccination is unknown due to lacking official registries. This study presents in a pragmatic frame the comparison of cervical pathology data between HPV-vaccinated and unvaccinated women referred for colposcopy. Materials and Methods: This is an observational prospective cohort study performed in 7 academic Obstetrics & Gynaecology departments across Greece between 2009-2019. Cases were women that had completed HPV vaccination before coitarche and were referred for colposcopy due to abnormal cytology. For each vaccinated woman an unvaccinated matched control was selected. Results: A total of 849 women who had been vaccinated before coitarche and 849 unvaccinated controls were recruited. The combination of cytological, colposcopic and molecular findings necessitated treatment in only a single case among vaccinated (0.1%) and in 8.4% among unvaccinated. Conclusion: Despite potential bias, this study’s message is clear: HPV vaccination at a proper age can markedly reduce development of severe cervical precancer and consequently, the need for treatments with their long-term related obstetrical morbidity
